SAFETY-SPOUT roe POWDER-KEGS.

' Application filed November 27, 1915.

To all whom it may concern:

Be it known that 1, Harrison H. DAVIS, a citizen of the United States,residing at The Plains, in the county of Athens and State of Ohio, haveinvented a new and useful Safety- Spout for Powder-Kegs, of which thefollowing is a specification.

The present invention relatesto improvements in safety spouts for powderkegs, one object of the invention, being the provision of a spout andmeans for attaching it to a powder keg, said spout being provided withan automatic closing valve whereby the same is normally closed tothereby seal the keg for excluding the atmosphere and sparks.

A further object of the present invention, is the provision of asafetyspout of the character indicated, the valve of which will be opened whenthe spout is applied properly-to a cartridge shell, the valve closingimmediately as soon as the spout is removed from the shell.

A still further object of the invention is the provision of a spout ofthe nature specifiedprovided with a cutting, keg entering end and meansfor securing the spout to the head of the keg, such means beingadjustable for kegs of various heights.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawing-Figure 1 is a perspective ,view of a keg with the presentsafety spout applied thereto. Fig. 2 is an enlarged vertical sectionalview through the spout, a portion of the tie rod being broken away toforeshorten the view. Fig. 3 is an enlarged sectional view of the outletend of the spout applied to a cartridge shell. Fig. 4 is an enlargedbottom plan view of the entering end of the spout and the rim engagingjaw thereof. Fig. 5 is an enlarged top plan view of the lower rimengaging jaw of the present device. Fig. 6 is a view similar to Fig. 3illustrating a modification.

Referring to the drawing, the numeral 1 designates the spout which isprovided with fipecification of Letters Patent.

the lower oblique cutting or entering end 2 adapted to be driven orprojected through the top of the keg or can C. The spout 1 is providedwith the powder directing bore or passage 3 and with one or more sideoutlets t adjacent the end 2.

An upper rim engagingjaw 5 is secured to the spout and to the upper endof a tie rod 6, whose lower end is exteriorly threaded, as at 7, and hasslidable thereon, the lower rim engaging jaw 8, the jaw 5 being providedwith the rim engaging groove 9, while the jaw S is provided with the rimengaging groove 10. The jaw 8 has a boss S surrounding the rod 6. Thegroove 9 engages the upper rim of the can while the groove 10 engagesthe lower rim of the can so that a lock nut 11 having the operatinghandles 12 may be threaded onto the lower end of the rod 6 to clampthe'jaws to the rims of the can. By this means, the device is readilyapplied to cans of various sizes, and the rod 6 has a handle 6 wherebythe can may be readily carried and handled. The spout ispreferablyconstructed of brass or other nonsparking material. Below the jaw 5 andsurrounding the cutting end 2 of the spout is a rubber or other gasket13 which, when the spout penetrates a can, is adapted to seat upon thecan around the opening or aperture cut by the end 2, to prevent leakage.

The upper or outer end of the spout 1 is provided with the angularly orobliquely disposed nozzle 14 which is provided with the internalinwardly-facing shoulder 15 at a point slightly ahead or beyond thejunction of the bore 3 with the bore 3 of the nozzle, while slidable inthe enlarged portion of the bore 3' behind the shoulder 15 is acup-shaped valve 16 normally held in the seated position, as shown inFig. 2, by means of the coiled expansion spring 17 entering the valveand held in place by means of the cap 18 threaded onto the rear end ofthe nozzle 14:.

WVhen using the present device, the keg or can with the spout 1 appliedthereto is inverted and the outlet end of the nozzle 14 is placed, asillustrated in Fig. 3, over an upstanding pin 19 carried by theapertured powder directing cap 20 engaged upon the powder receivingshell 21 of the cartridge, and the pin will therefore raise and unseatthe valve 16 against the tension of the spring 17 thus openingcommunication between the bores 3 and 3 so that powder may flow from thecan out of the spout. As soon as the spout 1 is raised and the valve 16is released from the pin 19, the spring 17 will cause the valve to seatagainst the annular shoulder 15 and thus cut oil the flow of powder fromthe bore 3 to the bore 3. Thus, an automatic closure device isprovidedfor the spout.

In'applying the present device to a keg or can, the nozzle 14: isgrasped by the hand and the cutting end 2 is forced through the top. ofthe can 0 adjacent the upper rim thereof, or so that the groove 9 may beengaged upon the rim when the cutting end 2 V is home with the gasket 13resting upon the top of the can and the apertures 4 below said top. Thejaw 8 is now placed upon the lower threaded .endof the rod 6 and the nut11 is screwed thereon so as to move the j aw8 and engage the groove 10thereof with the lower rim of the can and thus simultaneously draw thejaw 5 closely upon the upper rim. a

of the cartridge shell 21, and when the noz-' zle is depressed, thenozzle will seat on the plug 20 and the valve 16 will be unseatedtoallow the powder to flow into the shell 21. As soon as the spout isremoved, the valve is seated under the influence of its spring. In thisform, the valve unseating means is carried by the valve at all times,although either of the devices illustrated in Figs. 3 and 6 can beusedwith the present spout.

Having thus described the invention, what is claimed as new is 1. In adevice of the character described, a spout having an entering end, a jawattached to said spout and having a rim engaging groove, a tie rodhaving one end attached to said jaw, a second jaw slidable upon theother end of said rod and having a rim engaging groove, and a nutthreaded upon the last mentioned end of the rod for moving the secondjaw toward the first mentioned one for clamping a receptacletherebetween.

2. In a device of the character described, a spout having an enteringend, a jaw carried by said spout and having a rim engaging groove, asecond jaw having a rim engaging groove, a tie rod attached to one ofsaid jaws and slidable through the other, and means carried by said rodtoengage the jaw through which the rod is slidable for forcing said jawstoward one another to engage said grooves of the jaws with the end rimsof a keg.

3. In 'a device of the character described, a spout having portionsarranged at an angle with one another, one portion extending to oppositesides of the other, the first mentioned portion having a valve seatahead of the second mentioned portion, a spring pressed valve slidablewithin the first mentioned portion to seat against said seat and toextend across the second mentioned portion when seated, a pin carried bythe valve and projecting from the spout, and an apertured member carriedby said pin to fit a cartridge shell or vessel and to abut against theend of the spout when the valve is unseated by said pin.

In testimony that I claim the foregoing as my own, I have hereto afliXedmy s1gnature in the presence of two witnesses.
